Abstract

An image displaying method is provided. The image displaying method is utilized for displaying an image on a display region. The image has a first pixel and a second pixel respectively displayed on a first position and a second position in the display region. The image displaying method includes: deciding the first pixel according to a response time analysis, illuminating the first position and the second position according to a first brightness value of the first pixel; and adjusting brightness of the second position to a second brightness value of the second pixel.

1 . An image displaying method for displaying an image on a display region, wherein the image comprises a first pixel and a second pixel respectively displayed on a first position and a second position in the display region, the method comprising:
 deciding the first pixel according to a response time analysis;   illuminating the display region according to a first brightness value of the first pixel by an LED backlight; and   adjusting brightness of the second position to a second brightness value of the second pixel by controlling a corresponding LC unit.   
     
     
         2 . The method of  claim 1 , wherein the step of deciding the first pixel according to the response time analysis comprises:
 deciding a pixel in the image corresponding to a longest response time as the first pixel by analyzing the pixel value variation.   
     
     
         3 . An image displaying device for displaying an image on a display region, wherein the image comprises a first pixel and a second pixel respectively displayed on a first position and a second position in the display region, the device comprising:
 a deciding module, for deciding the first pixel according to a response time analysis;   an illuminating module, coupled to the deciding module, for illuminating the display region according to a first brightness value of the first pixel; and   an adjusting module, coupled to the illuminating module, for adjusting brightness of the second position to a second brightness value of the second pixel.   
     
     
         4 . The device of  claim 3 , wherein the deciding module decides a pixel in the image corresponding to a longest response time as the first pixel. 
     
     
         5 . The device of  claim 3 , wherein the illuminating module comprises a light emitting diode (LED) unit. 
     
     
         6 . The device of  claim 3 , wherein the adjusting module comprises:
 a liquid crystal (LC) unit; and   a driving unit, coupled to the LC unit, for twisting the LC unit to adjust the brightness of the second position to the second brightness value.   
     
     
         7 . A liquid crystal display (LCD) panel for displaying an image, comprising:
 at least a first display region and a second display region, displaying a first portion and a second portion of the image respectively, wherein each portion of the image comprises at least a first pixel and a second pixel respectively displayed on a first position and a second position in the corresponding display region;   a deciding module, for deciding the first pixel in each portion of the image according to a response time analysis;   at least a first LED unit and a second LED unit, coupled to the deciding module, for illuminating the first display region and the second display region respectively, wherein each LED unit illuminates the corresponding display region according to a first brightness value of the first pixel in the corresponding portion of the image;   a plurality of LC units; and   a driving unit, coupled to the LC units, for twisting a corresponding LC unit to adjust brightness of the second position in the corresponding display region to a second brightness value of the second pixel in the corresponding portion of the image.   
     
     
         8 . The LCD panel of  claim 7 , wherein the deciding module decides a pixel in each portion of the image corresponding to a longest response time as the first pixel. 
     
     
         9 . An image displaying method for displaying an image on a display region, wherein the image comprises a first pixel displayed on a first position, the method comprising:
 deciding the first pixel according to a response time analysis;   illuminating the first position according to a first brightness value by an LED backlight; and   adjusting brightness of the first position to a second brightness value by controlling a corresponding LC unit.   
     
     
         10 . An image displaying device for displaying an image on a display region, wherein the image comprises a first pixel displayed on a first position, the device comprising:
 a deciding module, for deciding the first pixel according to a response time analysis;   an illuminating module, coupled to the deciding module, for illuminating the first position according to a first brightness value; and   an adjusting module, coupled to the illuminating module, for adjusting brightness of the first position to a second brightness value.
